WINCC几个常用C语言编程

1、wiNccn个常用c语言编程WINCC 几个常用C语言编程全局脚本编程(按钮连续增减)说明：1、建立全局脚本函数2、建立全局动作C脚本3、在启动画面的打开画面中调用全局脚本函数4、在计算机的启动选项中选中全局脚本全局脚本函数InitAction ()externchar tagname30=""externSHORTcount = 0;externFLOATlow = 0;externFLOAThigh = 0;externFLOATste p = 0;void In itActio n()按钮左键按下连续增加externchar tag name30;externSHOR

2、Tcou nt;externFLOATlow;externFLOAThigh;externFLOATste p;strcpy(tagname," S32i_varia_but_04 ");count = 1;low = 0;high =1400;ste p =0.5;按钮左键按下连续减少externchar tag name30;externSHORTcou nt;externFLOATlow;externFLOAThigh;externFLOATste p;strcpy(tagname," S32i_varia_but_04 ");count = 2;

3、low = 0;high =1400;ste p =0.5;按钮左键松开停止增减extern SHORT count;coun t=0;全局动作 C脚本(counter.pas) #i nclude "ap defa p.h"int gscAction( void )externchar tag name30;externSHORTcou nt;externFLOATlow;externFLOAThigh;externFLOATstep;FLOAT value;if (cou nt=1)|(cou nt=2)/get current valuevalue = GetTagF

4、loat(tag name);/incif (co un t=1)value = value+ste p;if (value>high) (value=high); /high limit /ifif (co un t=2)/decvalue = value-ste p;if (value<low) (value=low); /low limit/ifSetTagFloat (tagname,value);/if return (0);全局脚本函数(InitAction )文件:C 脚本(counter. pas)文件:按钮左键连续增加文件:按钮左键松开文件:C脚本编程(按钮按击增

5、减)1、直接调用C动作方式实现:#i nclude "ap defa p.h" void On LButt on Dow n( char* IpszPi ctureName, char* lp szObjectName, char* l pszProp ertyName, UINT nF lags, int x, int y)FLOAT value;/check limitvalue=GetTagFloat("S32i_varia_but_00"); /get tag valueif (value>1300) (value=1400);else v

6、alue=value+100;/inc valueSetTagFloat("S32i_varia_but_00",value); /set new value2、调用函数方式实现(incdecvalue):FLOAT value;value=GetTagFloat ("S32i_varia_but_04");In cDecValue(&value,0,1400,100,1);SetTagFloat ("S32i_varia_but_04",value);项目函数(incdecvalue)void In cDecValue(FL

7、OAT *value,FLOAT low,FLOAT high,FLOAT ste p,DWORD a)FLOAT v;v=*value; /get current value switch (a)case0: if (v<step) (v=0); /low limitelse v=v-ste p;/decreme nt /case 0break;case 1:if (v>(high-ste p)(v=high); /high limitelsev=v+ste p;/in creme nt/case 1break;/switch *value=v; /return 项目函数(incdecvalue)文件:C脚本编程(按钮切换开关)： #include "apdefap.h" void On LButt on Dow n( char* IpszPi ctureName, char* lp szObjectName, char* l pszProp ertyName, UINT nF lags, int x, int y)BOOL state; /fl
